Absence of a serious medical complication (SMC) following 42 days after randomisation. SMC is defined as: Death; and/or ICU admission; and/or Septic shock requiring vasopressive therapy.

Study Overview

Brief Summary

The goal of this clinical trial is to compare a short course of antibiotics in patients in whom no bacterial infection is found with the current "golden standard": long-term antibiotic treatment in adult hematology patients who develop neutropenic fever.

The main question it aims to answer is: whether the short-term treatment is equally safe for patients, hence the name 'SAFE study'.

Participants will be randomly assigned (randomized) to one of two treatment options once they develop neutropenic fever: short-term or long-term antibiotic treatment. An additional blood sample, urine sample and stool sample will be collected.

Researchers will compare the short-term and the long-term antibiotic treatment groups to see if the short treatment is equally safe as the long-term treatment group.

Inclusion Criteria

  • •Voluntary written informed consent of the participant or their legally authorized representative has been obtained prior to any screening procedures;
  • •Age older than 16 years;
  • •Intensive therapy is started within three days before randomization for one of the following haematological conditions:
  • •Remission induction chemotherapy for newly diagnosed acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS); OR
  • •Re-induction chemotherapy for relapsed after haematological remission lasting for a minimum duration of 6 months; OR
  • •Conditioning regimen to prepare for an allogeneic HCT; OR
  • •Conditioning regimen to prepare for an autologous HCT.
  • •Expected longstanding (≥ 7 days) neutropenia (ANC < 0.5x10^9/L);
  • •Expected length of hospital stay of at least 10 days.

Exclusion Criteria

  • •Clinically or microbiologically documented infection;
  • •Patient already receives broad spectrum antibiotic therapy;
  • •Any critical illness for which Intensive Care Unit treatment is required;
  • •SOFA score ≥ 11;
  • •Longstanding neutropenia (>21 days) prior inclusion;
  • •Previous enrolment in this study;
  • •Not able to provide written informed consent;
  • •Any disorder, which in the Investigator's opinion might jeopardise the participant's safety or compliance with the protocol;
  • •Any prior or concomitant treatment(s) that might jeopardise the participant's safety or that would compromise the integrity of the Trial.

Arms & Interventions

Short treatment group

Experimental

Empirical broad-spectrum antibiotics (EBAT) as per local protocol:

  • Meropenem 3 x 1(/2) g IV; OR
  • Piperacilline-Tazobactam 4 x 4 g IV; OR
  • Cefepime 3 x 2 g IV; OR
  • Ceftazidim 3 x 2 g IV

Short treatment group: EBAT will be discontinued:

  • After 3x24 hours;
  • Irrespective of presence of fever; AND
  • If no clinical of microbiological infection is documented.

Intervention: Comparison short vs extended EBAT treatment group (Other)

Extended treatment group

Active Comparator

Empirical broad-spectrum antibiotics (EBAT) as per local protocol:

  • Meropenem 3 x 1(/2) g IV; OR
  • Piperacilline-Tazobactam 4 x 4 g IV; OR
  • Cefepime 3 x 2 g IV; OR
  • Ceftazidim 3 x 2 g IV

Extended treatment arm: EBAT will be continued:

  • At least 5x24 hours;
  • Until afebrile (TMT<38.0°C) for at least 5 consecutive days; OR
  • Until resolution of neutropenia (ANC >0,5 x109/L); OR
  • Until they have been treated 10 days, whatever comes first.

Intervention: Comparison short vs extended EBAT treatment group (Other)
